What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 2 of its 22 active ingredients.
  • “Protein Digesting Enzymes” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Fat-Digesting Enzymes” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “Lactose-Digesting Enzymes” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

Premium Certified Digestive Enzymes contains 22 active ingredients—a mix of enzymes that break down different parts of food. You've got amylase for carbohydrates, lipase for fats, proteases (acid protease, neutral bacterial protease, alkaline protease, and protease SP) for proteins, lactase for milk sugar, cellulase for fiber, and several others like phytase, glucoamylase, and beta glucanase.

The formula also includes BioPerine (black pepper extract) and betaine hydrochloride, which may help your body absorb nutrients better. There's one inactive ingredient: cellulose.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: digestive support and enzyme function.
  • We looked for evidence on: Dyspepsia, Flatulence, Lactose intolerance, Diarrhea, bloating, indigestion — and 2 related terms.
  • The strongest evidence on file: Lactase is rated "Effective" for Lactose intolerance (Natural Medicines).
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.
  • Also on file: Betaine Hydrochloride is rated "Insufficient Reliable Evidence To Rate" for Diarrhea, Dyspepsia.

The evidence for most of these enzymes isn't well established in the data we hold. Lactase is the exception—it's rated effective for lactose intolerance, so if you have trouble digesting milk products, that ingredient has proven benefit.

For the others—amylase, lipase, bromelain, and the various proteases—the effectiveness data shows insufficient evidence to rate their benefit. That doesn't mean they don't work; it means we don't have solid research backing their use for digestive complaints.

The evidence, ingredient by ingredient Bromelain Proteolytic Enzymes (proteases) Papain Lipase Lactase Betaine Hydrochloride Black Pepper Phytase

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 8 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these enzymes are generally well tolerated when used as directed. Bromelain is safe short-term, though long-term safety data is limited; it can cause diarrhea, gas, stomach upset, or headache in some people, and rarely allergic reactions.

Betaine hydrochloride may irritate your stomach and shouldn't be used if you have ulcers, gastritis, or acid reflux. Lactase is generally well tolerated; a rare allergy has been reported.

The proteolytic enzymes (the protein-digesting ones) may cause digestive upset or, rarely, allergic reactions. Black pepper is safe in food amounts, though concentrated supplements should be used cautiously.

For pregnancy, safety data are limited or absent for most ingredients here—bromelain, betaine hydrochloride, phytase, and the proteases should be avoided unless your doctor advises otherwise. Lactase is likely safe in pregnancy.

For breastfeeding, there isn't enough data for most of these; ask your pharmacist or doctor before regular use.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 4 of the 8 matched ingredients can interact with medications — Papain, Betaine Hydrochloride, Black Pepper, Bromelain.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,040 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with us before taking this if you're on propranolol, nevirapine, rifampin, phenytoin, cyclosporine, pentobarbital, atorvastatin, or theophylline—BioPerine can raise their blood levels (Moderate severity). If you take blood thinners or antiplatelet drugs like warfarin or aspirin, the bromelain in this product may increase bleeding risk (Moderate).

If you take H2-blockers, antacids, or proton pump inhibitors for acid reflux or ulcers, betaine hydrochloride may reduce their effectiveness (Minor). Run your exact medications through the search tool on this page.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a multi-enzyme digestive blend best suited for people with general digestive complaints or lactose intolerance. If you take heart medications, blood thinners, seizure drugs, or acid-reducing medications, check your specific prescriptions with us first—several ingredients here can interfere.

Pregnant or breastfeeding women should talk to their doctor or pharmacist before starting, since safety data are sparse for most components.

Likelihood Possible Evidence D
Atorvastatin (Lipitor)

Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D

Bromelain2 drug types · 141 drugs

Anticoagulant/Antiplatelet Drugs

Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.

Digestive Enzymes by Premium Certified: Common Questions

Does Digestive Enzymes by Premium Certified interact with any medications?
Yes. Based on its ingredients, Digestive Enzymes has a known interaction with 1,039 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Digestive Enzymes contains 22 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this help me digest food better?
These enzymes are designed to help break down different food components, but the evidence for most of them isn't well established in our data. Lactase—the milk-sugar enzyme—does have proven benefit if you're lactose intolerant. For the others, we don't have solid research yet, so results may vary.
Is it safe to take this if I'm on an acid-reflux medication?
Not without checking first. Betaine hydrochloride in this product increases stomach acid and may weaken your acid-reducer, whether it's an H2-blocker, antacid, or proton pump inhibitor. Talk to your pharmacist about whether this product is right for you.
Can I take this while pregnant?
Safety data are limited or missing for most ingredients here. Lactase is likely safe, but bromelain, betaine hydrochloride, phytase, and the proteases should be avoided unless your doctor advises otherwise. Check with your doctor or pharmacist before starting.
What's BioPerine doing in a digestive enzyme formula?
BioPerine is black pepper extract. It's thought to help your body absorb nutrients better. However, it can raise blood levels of certain medications, so it's important to check your prescriptions before taking this product.
What side effects might I experience?
Most people tolerate these enzymes well. The most common are digestive complaints like diarrhea, gas, or stomach upset. Bromelain can occasionally cause headache. Allergic reactions are rare but possible, especially if you're sensitive to plant enzymes. Stop and contact your doctor if you have unusual symptoms.
Is this product safe for breastfeeding?
There isn't enough safety data for most of these ingredients during breastfeeding. Ask your doctor or pharmacist before regular use to make sure it's right for you.
